Table 2.2 List of LED indicators

3.5 GPS AntennaConnect an active GPS antenna to the SMA female connector labeled "GPS" to enable reception of thesignal from GPS satellites. The antennamust be placed to have clear view to the sky.

Note: It may take several minutes till themodule gets a valid GPS position fix after it was switched on,especially if the position changed significantly while themodule was off. TheGPS system does not workindoors.

3.6 Power supplyIMPORTANT: Since the hardware version 2.0 the power supply circuits inside the module aregalvanically separated from the supply terminals and thus no special requirements for powersupply wiring apply.

Image 2.3 HW version indication

In hardware version 1.0 the device body is internally connected to the negative pole of the powersupply. Following rules should be kept in this case:


l The negative pole of the power supply is connected to the switchboard body.

l The negative terminal of the InternetBridgeNT is connected directly to the same point as the connectionabove.

l The grounding terminal of the InternetBridgeNT is connected directly to the same point as the connectionabove.

If this kind of wirig is not possible for any reason a galvanically separated DC/DC convertor must be used inthe InternetBridge power supply path.

3.7 WAN connectionTheWAN connection provides connection between the InternetBridgeNT and the user terminal (i.e.InteliMonitor, Web browser etc.). There are twomodes of theWAN connection: cellular and Ethernet. WANconnection type is to be adjusted via IB-NT Config in the SETTINGS->General menu.

Note: Both connectionmodes are not available at the same time.

3.7.1 Cellular modeIn cellular mode the built-in cellular modem is used to connect themodule to the Internet via the cellularnetwork. Data-enabled SIM cardmust be installed in themodule. See the chapter Cellular connection setupfor details about settings related to the cellular mode.

SIM installationInstall the SIM card into the holder (1). Push the button (2) with a blunt tool to release the holder, eject theholder by fingers from the holder housing, place the SIM card into the holder as described on the sticker(metal plates upwards) and insert the holder with the SIM card carefully back into the housing.

Note: The SIM cardmust be unlocked (PIN request after power-upmust be disabled). See the chapterCellular connection setup for details.


Image 2.6 Inserting SIM

AntennaInsert the antenna SMA male connector firmly into the connector labelled "Cellular" and screw the nut byhand to fix the connector parts together. Slightly tighten the nut using a flat wrench if necessary.

Note: The antenna cablemust not be interrupted by any terminals. If the cable from the supplied antenna istoo short buy an antenna with longer cable instead of prolonging it. Prolonged antenna cables may result inproblems with signal strenght or loosing the signal at all.

3.7.2 Ethernet modeIn ethernet mode the 10/100M ethernet interface is used to connect themodule to a local network andInternet. Built-in cellular modem is not used. See the chapter Ethernet connection setup for details aboutsettings related to the Ethernet connectionmode.

3.8 Controller connectionController connection type is to be adjusted via IB-NT Config in the General settings menu. If multiplecontrollers are connected to the InternetBridgeNT each controller must have different controller address.

4.1 IB-NT ConfigFor setup of the InternetBridgeNTmodule the PC program IB-NT Config is used. The program is installed bythe ComAp PC Suite installation package and is located in the program group "ComAp PC Suite", submenu"Tools". Please refer to the ComApweb pages to get the latest version of the package. The file Installationpackages content map will help you find the proper package.

IB-NT Config requires one of following operating systems: Windows XP SP3, Windows Vista orWindows 7,Windows 8 withMicrosoft .NET 3.5 SP1 framework. If you do not have already installed the framework inyour computer the installer will automatically launch installation from theMicrosoft web pages. Broadbandinternet connection is recommended for the installation. The framework and its' service pack can be alsoinstalled anytimemanually from theMicrosoft web.

The IB-NT Config can be connected using different connection methods.

l USB - used for initial setting. The connection uses virual COM port, so the devicemust be connectedfirst to your computer and then the virtual COM port is created. After that you can start the IB-NT Configand select the proper COM port. The virtual COM port driver is installed together with the IB-NT Config.

l Ethernet - can be used for later changes of the settings remotely by connecting to the static IP address ofthemodule.

l AirGate - can be used for later changes of the settings remotely using AirGate connection.

Factory default password is "0". It is highly recommended to change the password. Go tomenu SYSTEM ->Password to change the password. Lost password?Write down themodule serial number and passworddecode number that are displayed in the warningmessage and contact your distributor.


Image 3.2 Invalid password message window

After youmade changes in settings of themodule the changes must be confirmed and themodulemust berestarted. Use themenu SETTINGS->Write and Reset.

4.1.1 Save and load the settingsUsing themenu SETTINGS->Save to File the current settings can be saved into a XML file. This file can belater used to restore settings e.g. after themodule is replaced (menu SETTINGS->Load from File.

4.2 General settings

Image 3.3 General settings

Themenu SETTINGS -> General contains essential settings of themodule.

1. WAN connectonmode selects the communication interface which themodule uses for acessing theexternal network (Internet). Select Cellular if you want to use the built-in cellular modem or selectEthernet if you want to use the ethernet socket.


2. AirGate Enable switches AirGate protocol extension on and off. If AirGate is on then you can use"AirGate" connection type in ComAp PC tools.

3. AirGate Address specifies the AirGate address. Use "airgate.comap.cz".

4. Conntrollers connection type selects the communication inferface which is used for connection of thecontrollers.

Note: If CAN bus is used and there are other communication devices/bridges such as other , I-LB, IG-IBor InteliVision-8(CAN) the CAN address collisionmust be avoided, e.g. each devicemust use differentCAN address.

Example: If you want to use two InternetBridgeNT with SIM card from two different operators at onesite and connect them via CAN bus then configure one InternetBridgeNT to CAN, Addr#1 and theother to CAN, Addr#2.

Option Physical CAN address

CAN, Addr#1 124

CAN, Addr#2 123

CAN, Addr#3 125

CAN, Addr#4 122

Table 3.1 Assignment of physical CAN addresses

Note: For using address 3 and 4 the setpoints CANAddrSwitch1 resp. CANAddrSwitch2must beswitched to OTHER in all connected controllers.

5. If RTC Synchronization is enabled the InternetBridgeNTmodule will synchronize the RTC clock of theconnected controllers with accurate time obtained from either GPS or Internet (NTP servers)


4.3 Ethernet connection settings

Image 3.4 Internet protocol settings

Themenu SETTINGS->Ethernet connection contains settings related to the ethernet WAN interface.Settings in this menu do not take place if theWAN interface is switched to cellular modem. For currentlyused IP address and other IP related settings (independently on type of theWAN interface type) go to themenu STATUS.

1. IP Address Mode selects whether you want themodule to work with manually adjusted static IP addressand other IP-related settings or you want themodule to get all settings automatically from aDHCPserver. See details about static IP address in the chapter Setting-up static IP address.

2. IP Address adjusts the static IP address of themodule in manual mode or displays the IP addressassigned by DHCP server in automatic mode.

3. Network Mask adjusts the network mask inmanual mode or displays the network mask obtained fromDHCP server in automatic mode.

4. Gateway IP adjusts the gateway address in manual mode or displays the gateway address assigned byDHCP server in automatic mode.

5. DNS Server IP adjusts the DNS server address in manual mode or displays the DNS server addressassigned by DHCP server in automatic mode.


4.4 Cellular connection settings

Image 3.5 Cellular settings

Themenu SETTINGS->Cellular connection contains settings related to the built-in cellular modem.

1. Network Selection is used to select manually the cellular operator or switch themodem to automaticselection. It is recommended to use automatic mode except e.g. if you want to avoid roaming or if youwant to select manually the network type (see setpoint below).

2. Network Type is used to select manually the nework type (2G or 3G) or leave the selection to be doneautomatically by themodule according to signal strength. The 3G network is preffered in automaticmode. If the network type is adjustedmanually then also the network itself must be selectedmanually(setpoint above).

3. Access Point Name is used to enter name of the internet access point. The proper name should beprovided by the SIM card operator, however, the name "Internet" works in most cases.

4. In rare cases the cellular provider might require also using APN User Name and APN Password for theparticular APN.

5. SIM PIN Status shows the current status of the SIM PIN lock. The SIM cardmust be unlocked (i.e. mustnot require PIN after switching on) to work properly in InternetBridgeNT. If the SIM is locked, press thebutton Unlock and enter correct PIN code. This will unlock the card and disable PIN lock for the future.

Note: It may take couple of minutes after powering themodule up till IB-NT Config shows the current SIMstatus. Then it may take couple of minutes again after entering correct PIN till the SIM is unlocked.


IMPORTANT: If manual network selection is used it might happen that the InternetBridgeNT willlose the internet connection as a result of change of the coverage of the particular network type(2G or 3G). This might be caused by reconfiguration of the network, network maintenance etc.

4.5 E-mail and SMS settings

Image 3.6 E-mail settings

Themenu SETTINGS->E-mail and SMS contains settings related to sending active e-mails and SMS.

1. InternetBridge-NT E-mail Address specifies the address which will appear as sender's address in activee-mails. This address must be valid, i.e. the domain namemust exist and the SMTP server must be ableto convert it to IP address. Otherwisemost of SMTP servers will refuse sending such e-mail.

2. SMTP Server specifies the IP address or domain name of the SMTP server, which is used for sending e-mails. TCP port number used for SMTP communication can be specified by adding colon and portnumber at the end ot the SMTP server name or IP address. If the port number is not specified the defaultnumber 25 is used.

Example: smtp.mydomain.com:9925

Note: In most cases Internet providers have their own SMTP servers, that are available for free for theircustomers and are accessible only if the e-mailing device is connected to the Internet via the respectiveprovider.

3. SMTP Authentification selects whether the SMTP server requires login or not. If yes the two setpointsbelow are used to enter username and password. Authentication types PLAIN, CRAM-MD5 aresupported. Encrypted connection is not supported.

4. SMTP User Name for STMP servers which require authentication (e.g. public paid servers).


5. SMTP Password for STMP servers which require authentication (e.g. public paid servers).

6. Time Zone is used to adjust time zone where the site (bridge) is located. This is necessary for therecipient's e-mail client to recalculate time and date of sending to the local time of the recipient. Theadjusted time zone is be used for conversion of the GMT time obtained from GPS or NTP into local timebefore the time is synchronized into the controllers.

4.6 GPS setting

2. SNMP Trap Dest. Address adjusts the IP address to which themodule sends SNMP trap if there is anew item in AlarmList in any of attached controlers.

3. SNMP Read Community adjusts the community string for reading data. The connected SNMP managermust use the same string when it attempts to read any data from the agent.

4. SNMPWrite Community adjusts the community string for writing data. The connected SNMP managermust use the same string when it attempts to write any data into the agent.


4.9 Other settings

Image 3.10 Other settings

1. ComAp protocol TCP port adjusts the port number used for Direct IP or AirGate connection. The defaultport is 23 and should not be changed unless there is a clear reason for the change. A typical reasonmightbe a need to share of one static public IP address amongmultiple devices behind a router which performsNAT.This setting applies for both AirGate and direct connectionmodes.

2. AirGate UDP port adjusts the port number used for registration into AirGate. The default port is 6127 andmust not be changed unless you are using a private AirGate which is configured to a different UDP port.

IMPORTANT: If AirGate is used the ComAp protocol TCP port must be adjusted to port 23 oralternative port 21. Any other value will cause the communication will not work.

4.10 Firmware update4.10.1 InternetBridgeNT firmware update

5.8 Time synchronization 40

5.1 Direct IP connectionDirect IP connection is intended to be used if the InternetBridgeNTmodule is reachable from the clientcomputer by specifying the IP address at which themodule can be contacted. If direct connection is to beused within a local network the InternetBridgeNTmust have static IP address in the respective local nework.If direct connection is to be used from the Internet, the IP address, which is entered into the client computer,must be static and public in scope of the Internet.

In most cases if themodule is connected to Internet via a local ethernet network port forwardingmustcreated from the public IP address of the network gateway to the local IP address of InternetBridgeNT at theport specified for ComAp protocol. Different port numbers can be used to createmultiple port forwardingrules in the same local network. If InternetBridgeNT is connected via cellular network the SIM card withstatic and public IP address must be purchased.

Note: In InternetBridgeNTfirmware versions below 1.2 the direct IP connection can not be used if AirGateconnection is enabled.

Maximum of 3 clients of ComAp type (InteliDDE server, WinScope, WebSupervisor) can be connectedsimultaneously to themodule.

Note: If you have troubles with setting up static and public IP address for direct connection from Internetuse AirGate connection instead.


Image 4.1 Direct connection in a LAN

Image 4.2 Port forwarding example

5.1.1 Setting-up static IP addressThis chapter describes how to setup the InternetBridgeNTmodule to a static IP address. Static IP address isrequired if following functions (connection types) are to be used:

l Web interface

l Direct IP connection

l MODBUS/TCP

There are two basic ways to get the static IP address:

First way is to switch the InternetBridgeNT to manual IP address mode and adjust all IP settings (IPaddress, network mask, gateway IP address and DNS server IP address) manually using IB-NT Config. Ifthis method is used several basic rules should be kept to avoid conflicts with the remaining networkinfrastructure:


l The static IP used in the controller must be selected in accordance with the local network in whichInternetBridgeNT is connected.

l The static IP used in the controller must be excluded from the pool of addresses which is assigned byDHCP server, which is in charge of the respective local network.

l The local infrastructuremust generally allow using devices with manually assigned IP addresses.

l Theremust not be any other device using the same static IP address. This can be tested from acomputer connected to the same network using ping command issuedfrom the command line. The IP address is not occupied if there is not any response to the ping command.

Note: The list above contains only basic rules. Other specific restrictions/rules may take place dependingon the local network security policy, technolgy used, topology etc.

Next way is to switch the InternetBridgeNT to automatic IP address mode and let InternetBridgeNT to get IPsettings from the DHCP server. Then configure the DHCP server to assign always the same IP address(i.e. static IP address) to the particular InternetBridgeNT according to it's MAC address. InternetBridgeNT

MAC address is displayed in IB-NT Config, menu System->Device Info->Ethernet MAC address, as well asprinted on the ethernet socket.

IMPORTANT: It is strongly recommended to consult using static IP address with the localnetwork administrator.

5.2 AirGate connectionAirGate connection is recommended if you want to access the bridge using ComAp protocol (i.e. ComAptools like InteliMonitor, GenConfig orWebSupervisor) and the bridge does not have fixed IP address and/orthere is no route from the client computer to the bridge.

AirGate is to be activated in the General Settings menu. When the InternetBridgeNT connects to the AirGatefirst time it is registered into the AirGate database and gets AirGate ID, which remains then the same even ifthemodule is switched off and on again. This AirGate ID is used for all controllers connected to theInternetBridgeNT, the controllers are distinguished from each other by their controller address. AirGate ID isdisplayed in IB-NT Config (STATUS->WAN Connection->AirGate ID).

Max. 2 clients of ComAp type (InteliDDE server, WebSupervisor) can be connected simultaneously.

5.3 Web interfaceThe web interface is intended tomonitor the site from aweb browser. Static IP address is required for thisfunction as youmust know the IP address to put it into the browser. Public IP address or port forwarding isrequired if you want to see the web pages from the Internet.

Maximum of 2 web clients can be connected simultaneously.


Image 4.3 Port forwarding example for web connection

The web server is designed for basic monitoring and adjustment of the controller using a web browser. Justput the InternetBridgeNT IP address into the browser to display the overview page with the list of connectedcontrollers. Then click to a controller to see it's web pages. You will asked for the controller access codeprior to entering the controller web.

The logo displayed on the top of the web page is customizable. See the chapter Customizing the logo..


Note: Do not openmultiple web connections to the same InternetBridgeNT from the same browser windowusing browser tabs. This may cause that the data in te tabs will bemixed-up. Do not use the browsernavigation buttons as "Back", "Forward" or "Reload". Use the links and the reload button located in thetoolbar instead.

These settings will be also applied for the web pages of the other controllers connected to theInternetBridgeNT.

5.4 Active e-mails and SMSThemodule can send active e-mails and sms from the connected controllers if the controller is adjusted tosend it. The controller setpoint groupAct.calls/SMS contains all settings related to this function:

1. Selection of events (alarm types) that will issue active e-mail or sms.

2. Seletion of message type (e.g. e-mail or sms) for each channel.

3. Entering the destination address (e.g. e-mail address or phone number) for each channel.

There are several settings in the InternetBridgeNT itself that are required for proper sending of e-mails. It is,above all, SMTP server address and InternetBridgeNTmailbox (sender's e-mail). See the chapter e-mail andsms.

The function of sending active sms is available regadless of WAN connection type. IT requires only a SIMcard with properly adjusted SMS center to be inserted in themodule.

5.4.1 Languages in SMS and e-mailsThe required language, in which the active e-mail or SMS is to be sent, is adjusted in the controller viasetpoint Acall+SMSlang.

l Sms in languages with code page from the list below (except Latin 1) are converted to UCS-2 encodingand sent as "short" sms (70 characters).

l Sms in languages using Latin 1 are converted to 7-bit GSM encoding (accents are removed from thecharacters) and sent as "long" sms (160 characters).


l E-mails are sent in ASCII using "Base64" encoding. The e-mail header contains information about theused code page. "8BITMIME" is nomore required.

l Standard SMTP protocol is used if no authentication is required by themailserver.

l ESMTP protocol is used for servers requiring authentication. "LOGIN" authentication type is supported.

l If code page for the adjusted language is not in the list e-mails and sms are sent in english.

Table 4.1 List of supported code pages

5.5 MODBUS/TCPMODBUS/TCP protocol is used for integration of the controllers into a buildingmanagement system or forremotemonitoring via 3rd party monitoring tools. TheMODBUS/TCP protocol is to be enabled/disabled inthe setup pageMODBUS, setup itemMODBUS/TCP Protocol. TheMODBUS protocol is enabledalternatively with the SNMP protocol, so both protocols can not be active simultaneously. Max. 1MODBUS/TCP client can be connected in onemoment.

l Functions 3,6,16 are supported.

l Use the value of controller address setpoint as MODBUS "device address" to specify for whichparticullar controller theMODBUS query is directed.

l Themap of registers depends on controller firmware branch, version and configuration. It can beexported into a text file from the appropriate controller archive using GenConfig.

l Some registers have fixedmeaning. These registers, as well as much other information regardingMODBUS including examples, are available in the Communication guide at the ComApweb site.

Note: If the InternetBridgeNT is connected to the controller(s) via RS485/RS232 the number of registers thatare read in one query is limited to 62.

Controller access codemay be required to start MODBUS/TCP session. Use function 16, register 46339and number of registers 8. The access code is a null-terminated string of max. 15 characters. Send the 1stcharacter in the LSB of the 1st register, 2nd character in theMSB of the 1st register, 3rd character in the LSBof the 2nd register etc. It is possible to disable requiring the access code using the setup itemMODBUSAccess Code.


5.6 SNMPThe controllers connected to the InternetBridgemodule can be contacted also via SNMP v.1 protocol. Thebridge acts as a SNMP agent and provides controller data for the remote SNMP Manager as well as sendsTRAPs always when a new alarm appears in the controller alarm list. The SNMP Agent function is to beenabled/disabled in the setup page SNMP, setup item SNMP Protocol. The SNMP protocol is enabledalternatively with theMODBUS protocol, so both protocols can not be active simultaneously.

l Each controller has it's ownMIB table which is to be created from the controller configuration usingGenConfig (menuGenerate cfg image -> Generate SNMP MIB Table).

l If there is a new alarm in any of connected controllers the bridge sends a TRAP to the predefined IPaddress (SNMP -> SNMP Trap. Dest. Address. The trap has meaning "New alarm appeared" and as thebindings contain the alarmlist of the controller where the alarm appeared as well as the controller nameand serial number.

l SNMP read/write community strings are set by default to "public"/"private" and can be changed in thesetup page SNMP.

l TheMIB table is fixed, can not be configured.

IMPORTANT: As the OID tree contains serial number of the controller it is absolutely necessarythat the MIB table is created from the configuration downloaded from the respective controller. Ifthe MIB is created from default archive or archive downloaded from other controller the SNMPagent will not report error.

5.7 GPSInternal GPS receiver can be used for location and tracking of themodule.

l TheGPS function is to be enabled/disabled in IB-NT Config, menu Settings -> GPS.

l The position data are available in IB-NT Config, menu Status -> GPS as well as in the connectedcontrollers.

l It is also possible to see the current position of the controller inWebSupervisor map view.

Note: The controller firmwaremust support GPS location to see the position in it or in theWebsupervisor.This support will be available from version 2.7 of IG-NT and IS-NT standard branch.

5.8 Time synchronizationInternal clock of themodule is regularly synchronized with either GPS time or Internet time (frompool.ntp.org). This synchronization provides accurate GMT time, which is used for timestamps in theoperation log and after shifting according to the adjusted time zone (menu Settings -> E-mail and SMS) alsofor e-mails to indicate at which time the e-mail was sent.

If synchronization of the controller RTC clock is enabled (menu Settings -> General -> Controllers) themodule will also readjust regularly the RTC clock of the connected controllers to the accurate time obtainedfrom GPS or Internet and shifted according to the time zone and eventually shifted also to daylight savingtime. The time zone is taken as above from the InternetBridgeNT settings, the daylight saving time shift isapplied if it is currently active in the controller.

Note: The controller firmwaremust support the RTC clock synchronization. This support will be availablefrom version 2.7 of IG-NT and IS-NT standard branch.


6 TroubleshootingWhere is the IB-NT Config software? How can I get it?

Cause Solution

The software is located in the program group "ComAp PC Suite", submenu "Tools". It isinstalled by the ComAp PC Suite installation package, please refer to the ComApwebpages to get the latest version of the package. The file Installation packages contentmap will help you find the proper package which contains the latest IB-NT Configversion.

Downloadtheinstallationpackage andinstall thesoftware.

I can not connect to the module from IB-NT Config.

Cause Solution

There is not any COM port labelled"InternetBridge-NT ComApUSB Device" in thelist.

Switch on themodule, connect the USB cablefrom themodule to your computer and wait untilthe USB devicemanager installs the drivers. Thenrestart IB-NT Config.

The USB devicemanager reports amessage thatthe connected device was not recognized and willnot work properly when I connect InternetBridgeNT

to my computer.

The device driver is missing or not installedproperly. Please reinstall the IB-NT Config.

The IB-NT Config displays message "Open COMError" when I am trying to connect to myInternetBridgeNT.

Check if there is not other IB-NT Config running inyour computer, which is connected to the sameCOM port.

Close the IB-NT Config, detach and attach theUSB cable and try to connect again.


The LED "Controllers" does not come up within several seconds after switching the power on.

Cause Solution

The wiring is notcorrect orterminatingresisors are notproperly installed.

Check the wiring according to the chapter Controller connection. Check if there areterminating resistors at both ends, but not anywhere else . Note, that most ofComAp products have internal terminating resistors that are to be activated byjumper. Check if there isn't the juper accidentaly set in some device connected inthemiddle of the bus.

Selectedcommunicationinterface does notmatch the onewhich is reallyused.

Use IB-NT Config to check the port selected for controller connection. You will findit in themenu SETTINGS -> General .

The CAN busmode is notadjusted in allcontrollers to thesame value.

Check in all controllers connected to the bridge if the setpoint "CAN bus mode" isadjusted in each controller to the same value.

There is acontroller addresscollision.

Adjust the setpoint "Contr. address" in each controller to a different value.

The module is switched to cellular mode but the LED "Cellular" does not come up withincouple of minutes after switching the power on.

Cause Solution

SIM card is not inserted properly. Check if the SIM card is installed as described in the chapter SIMinstallation.

SIM card is locked. Use IB-NT Config to unlock the SIM card with the PIN code asdescribed in the chapter Cellular network setup.

SIM card does not support internetconnection.

Ask your SIM card provider for help. If you are in doubts, you cantry using the card in an other internet-enabled device such as asmartphone.

Incorrect access point name. Ask your provider for proper APN name and then use IB-NT Configto change it.

The signal of the selected networkoperator is too weak or notavailable at all. Use the IB-NTConfig to check the signalstrength (STATUS -> Wireless ).

Check if you do not manually selected an operator or network typewhich is not available at current position. Themanual operatorselection should be used only to prevent roaming in situationswhere there is signal from home operator as well as from roamingoperators in the same location.

Try moving the antenna to different position or using antenna withhigher gain.


The module is switched to AirGate mode but the LED "AirGate" does not come up witincouple of minutes after switching the power on.

Cause Solution

AirGate address is notadjusted correctly.

Check if the AirGate address is adjusted to "airgate.comap.cz".

Themodule does not haveaccess to the Internet.

Check if themodule is properly attached to the Ethernet LAN

Check if themodule is attached to the cellular network. LED cellular mustbe on - either yellow or red. If the LED is not on see the symptom above.

There is a problem withtranslation of the AirGatedomain name to the IPaddress.

If the Ethernet parameters are assignedmanually check if they areadjusted correctly according to what you got from the LAN administrator.

If themodule is switched to get the parameters from aDHCP servercheck if it has received the parameters correctly. If there is a problem withDHCP server the currently assigned IP address would be "0.0.0.0".

If cellular connection is used check if the APN is set correctly as givenfrom your cellular provider.

Outgoing UDP traffic fromthemodule to the AirGateat port 6127 is disabled.

If cellular connection is used ask your provider whether outgoing UDPtraffic at port 6127 is enabled. If no, ask for enabling it or ask ComAptechnical support for alternative TCP port setting.

If ethernet connection is used ask the IT manager for enabling outgoingUDP traffic at port 6127.

The module is switched to AirGate, the LED "AirGate" came on, the module displaysAirGateID in IB-NT Config, but it is not possible to connect to the controllers fromInteliMonitor. DDE server reports error "Can't read IB version".

Cause Solution

Outgoing TCP traffic from themodule tothe AirGate at port 23 is disabled.

If cellular connection is used ask your provider whetheroutgoing TCP traffic at port 23 is enabled. If no, ask forenabling it or ask ComAp technical support for alternativeTCP port setting.

If ethernet connection is used ask the IT manager forenabling outgoing TCP traffic at port 23.

The module does not connect to AirGate if static IP address is used.

Cause Solution

The IP address, network mask, gateway addressand/or DNS address are not adjusted correctly.

See the chapter Setting-up static IP address forinformation about how to set-up a static IPaddress.


The connection to Internet via cellular network (especially 3G) is unstable and dropouts oftenoccur although the signal strength is sufficient. There are messages "Cellular connection reset05" in the log.

Cause Solution

The integrated cellular module is running firmware1.002, whichmay be unstable at 3G networks.

Update the cellular module firmware to 2.003

Message "Cellular connection reset 02" appears in the log. This message is written ifInternetBridgeNT does not have access to Internet.

Cause Solution

If this message appears only rarely it may be causedby automatic deactivation of the packet dataconnection by the cellular operator. InternetBridgeNT

detects this situation re-creates the connection again.

This is not a faulty situation.

If this message appears regularly each severalminutes it means InternetBridgeNT can not access theInternet at all. It may happen e.g. if InternetBridgeNT

operates in an isolated VPN.

It is not possible to operate InternetBridgeNT

(version up to 2.1) in cellularWAN connectionmode without Internet access. This possibilitywill be added into one of future versions.

Message "Cellular connection reset 00" appears in the log. This message is written ifInternetBridgeNT could not initialize the internal cellular modem.

Cause Solution

Rare occurence of this message can be a consequenceof a previous problem with the internal modem.

InternetBridgeNT will automatically reset themodem to recover from this situation.

Repeated occurence of this messagemeans the internalcellular module is damaged.

Factory repair is needed.
